.Application filed September 30, 1916. Serial No. 123,001.

To all w/wm may concern: it known that L ANDREW SADLOCK, a "u the UnitedStates, residing at in the `county of Fayette and lit venia, haveinvented cerain new at. u. il Improvements in Elevatingdaoks, or whichthe .following is a specification.

This invention relates to certain new and useful improvements inelevating jacks.

.lhe primary objectoif the device is the provision of lifting jackespecially adapted for u'se with automobiles, the same being providedwith adjustable axle-receiving members whereby the entire end oli avehicle may be readily elevated as found desirable. A further object oftheldevice is the `provision, of a lifting jack having an adjustablestop limiting means for the vertical movements got the vehiclesupporting meniher, such member being freely revolnble and capableoflateral tilting, shiftable load-receiif'ing means being carried by the4said member. 1

. it. still further object of the device is they provision. of a jaclithat'is easy and inem 'pensi-ve to manufacture, the saine being capableof elevating a weighted body tilt-` a'bly and revolubly positioned,ineens being arranged llor supportingbodies of different dimensions.,With these general obiects in view and others that will appear as thenature of the invention is better understood, the sama een sists in .thenovel construction, combination and arrangement of partshereinafter morefully described,' illustrated in the aeeonipanying drawings, and thenclaimed.

In the drawings forming a part of this application and in which likedesignating characters refer lo 'corresponding parts throughout theseveralviews r-Figure 1 is a front' elevation of the device partiallybroken away. Fig. 2 is va side elevation thereof. Fig. 3 is a top planview of thel same. Fig. 4t is a longitudinal sectional View taken uponline IV-IV of Fig. 3'. through the supporting platform. Fig. 5 is aperspective view of the supporting platform detached, and Figs. 6 and 7are perv spectire views of the two adjustable slides employed with theplatform.

The .present device provides a standard 10 of inverted U-shapedarrangement having projecting feet l1 while three parallel lbraces 12are arranged within the said standard connecting the sides thereotogether. central perforations 13' in alinement with each other throughwhich a threaded shaft lit is freely arranged. An operating sleeve 15 isscrew-threaded upon the shaft 1-l between the top cross head 16 of thestandard 10 andl the uppermost brace l2, a pinion..

17 being carried by the sleeve 15 in'constant mesh with a gear 1S upon astub shaft '19 journaled in one side of the standard l0 and arrangedwith a turn crank .20. 1

A pivotv block 21 is swivelly connected with the upper end of the shaft14 as at 22 while a work holder or supporting platform 23 is pivoted tothe block 21 by a pintle 24e.

A main slide having longitudinal side flanges 26 is longitudinallyslidably arranged upon the platform 23 with its flanges positionedbeneath the inwardly projectingoverlying angular sides 27 of the saidplat-` form. An auxiliary slide 28 is longitudinally shiitably arrangedWithin an under-- neatli groove29 olf the aforementioned slide25,",Whereby both of the slides form a mounting 'lidjlistable in lengthupon the platforml 28,' as best illustrated in `Figs. 8 and 4 of thedrawings. A set screw 30 extends' through a threaded opening Sl'in themain slide 25 being adapted for engaging the adjacent face of theauxiliary slide 28 which auxiliary slide is thereby frictionally`enkgaged with the platform 23, the slides being in this manner retainedin their 'adjusted positions upon the platform 23.

Ltshaped supporting sockets 32 are provided 'with threaded Shanks 33vertically adjustably positioned adjacent the opposite free ends of thesaid slides. j

It Will be understood from this descripL tion of the device thatthe-platform 23 is laterally pivoted as Well as rotarily mounted uponthe shaft 11i, the latter being readily moved vertically by turning thecrank 20. The socket members 32 are designed for receiving an elongatedmember. such as an automobile axle, being capable of adjustmentl forattachment to uneven portions thereof While the'longitudinaladjustability of the slides and 28 allows the socket members 32 to bereadily adjusted with the Work positioned therein While the Set screwretainsthe slides so adjusted. The Work may then be tilted upon -thelpivot pintle -24 or lturne'd upon the swivel 'bonnection 22. A collar84: is adjustably mounted upon-the The braces 12 are provided with 1. Ajack comprising a standard, an o1 erating shaft carried by the saidstandard, a block swiveled in the upper `free end of the said shaft, a.4latform ivfitally mounted upon the said lock havmg inturned sidesadjacent 'the top thereof, a main slide mounted upon the top of the saidplatform having side flanges arranged beneath the said sides and havingan underneath recess, an auxiliary slide positioned upon the top of thesaid platform slidably arranged within the said recess, and anadjustment retaining means for the said slides.

2. A jack comprising a standard, an operating shaft carried by the saidstandard, a block swiveled in the upper free end of the said shaft, aplatform pivotally mounted upon the said block having inturned sidesadjacent the top thereof, a main slide mounted upon the top of the saidplatform havin side flanges' arranged beneath' the said sldes and havingan underneath recess, an auxiliary slide positioned upon the1 top of thesaid'platform slidably arranged within the said recess, an adjustmentretaining means for the said slides, and U-shaped work receiversprovided with threaded shanks adjustably arranged through the oppositievfree ends of the said slides.

In testimony whereof I ax mysignature.

ANDREW sADnooK.
